The Researcher Green hollow fiber membrane products incorporates our latest glycerin free low extractables modified polyethersulfon membrane technology. All Green Line products are gamma irradiated and ready to use without any tedious prerinse. The Green Line hollow fiber products from WaterSep are true plug-and-play at its best. Connect-Use-Discard!
The extractables level for the Researcher Green Line is approximately 80x less than a glycerin conditioned membrane. After a quick buffer conditioning the HF cartridge is ready to use.
The Researcher Green hollow fiber cartridges are positioned between the laboratory scale Explorer Green and the full pilot scale Investigator Green cartridges. The membrane surface area is between 444 cm2 for the Researcher12 Green and up to 1,715 cm2 for Researcher41 Green and are the perfect choice for scale up/scale down studies and preparative biopharmaceutical work with sample volumes between 400 ml up to 8000 ml.
The Researcher Green cartridges are available with molecular weight cut-off from 3K to 750 K and 0.1 µm, 0.2 µm and 0.45 µm and with the same path length as all other WaterSep HF cartridges which makes scale up/scale down exact and predictable.
Typical Applications:
- Clarification of cell culture and fermentation suspensions in primary recovery applications
- Cell harvest, excellent results have been achieved with both whole cell e. coli and e. coli lysates, as well as other microbial process streams
- Concentration and purification of vaccines
- Concentration/diafiltration of monoclonal antibodies, recombinant proteins, biological macromolecules and peptides
Recommended batch volume for Researcher24 Green: 0.7L-4L with a permeate flow rate of 2.5 L/h.
